Advances in wireless technology and affordable info-appliancesare making mobile computing a reality. Suchappliances can both communicate with a fixed station orwith other info-appliances in an ad-hoc manner. In bothscenarios the transaction paradigm is vital to provide applicationswith consistent access to durable data.However, current mobile transactional systems fail toprovide the so much needed adaptability to the large set ofusage scenarios and applications semantics (e.g. disconnectedwork, relaxed ACID properties, etc.).We present a transactional object-based mobile system,called MobileTrans, that supports the definition and enforcementof transaction policies. Such policies are separatedfrom the application code and specify transactionsbehavior: (1) how data is fetched, (2) how updates areperformed, (3) the degrees of consistency and atomicity required.Transaction policies can be either declarative (e.g.XML) or programmatic (e.g. Java, C#).
